' SAUSAGE-STUFFIN G MACHINE.

Specification of Letters Patent.

Application filed January 9, 1907. Serial No. 851,498.

To all whom it may concern:

Be it known that I, EDWARD J .HALLAHANH a citizen of the United States,residing at Augusta,, in the county of Richmond and State of Georgia,have invented new'and useful Improvements in Sausage-Stuffing Machines,of which the following is a specification;

This invention relates to a sausage stuffing 'machine, and aims toprovide a machine of such class with means hereinafter set forth topermit of the automatic return of the forcing piston and head by gravitywhen occasion so re uires.

A further ob ect of the invention is to pro vide a machine of such classwith means for automatically discontinuing the operation ,thereobwhenthe forcing piston and head have arrived at the limit of their stroke inone direction. I

A further object of the invention is to provide a machine of such classwith means to prevent leaking of the motive fluid from around the pistonduring the operation of the -forcing piston and head.

A further object of the invention is to provide the forcing piston headin a machine of such class with a packing whereby the tight fit betweeninner face of the material containing cylinder and the piston head isabove the top of the piston head thereby enabling the packing to' removeany matter adhering to the inner face of the cylinder.

A further object of the invention is to ro vide a forcing piston andhead in a mac ine of this class with means whereby said piston and headcan be readily removed when occasion so requires.

I A further object of the invention consists in providing a sausagestufii'ng machine which shall be simple in its construction, operated bymotive fluid, preferably water, strong, durable, efficient in its use,conveniently operated, having its operation automatically stopped whenoccaslon so requires, readily set u and comparatively inexpensave tomanu acture.

With the foregoing and'other objects in view, theinvention consists inthe novel construction, combination, and arrangement of partshereinafter more-specifically described andillustrated in the accomanying draw: mgs, wherein lsshown the pro erred embodiment of theinvention, but it is to beunderstood that changes, variations, andmodifications can be resorted to which come within the scope oftheclaims hereunto appended.

In describing the invention in detail reference is had to theaccompanying drawings, wherein like reference characters denotecorvlews, and in which Figure 1 1s a vertical sectional view of asausage stufiing machine in accordance with this invention. Fig. 2 is aplan with the material containing cylinder removed. Fig. 3 is a plan ofthe automatic stop mechanism responding parts throughout the" severalwith certain portions of the machine shown in dotted lines. Fig. 4 is aperspective of the automatic stop mechanism. Fig. 5 is a sectional viewof the piston packing. Fi

'6 is'a sectional detail of one of the chec Fig. 7 is a plan of one ofthe checkvalves. valves,' and Fig. 8 1s a detail showing the handle forremoving the forcingpiston and head.

Referring to the drawings b reference characters, 1 denotes the materiacontaining cylinder which is open at its bottom and provided atitstop-with a cover. 2 detachably secured in position by the holdfastdevice 3. Communicating with the to of the cylinder 1 is a dischargespout 4 to w ich the sausage casing is attached, and the said spout'4 18provided with a suitable cut-ofi 5.

Within the cylinder is'arranged a reci ro- A catory forcing 1piston towhich is secure the plate 7 a eather packing cu 8 whic projectsforwardly of the piston ead 6 so that the joint between the cylinder 1and the piston head will be had above the upper face thereof. Theprojecting ortion of the cu 8 acts as a means to clean t e inner face oft e cylinder from any material adhering thereto when the piston isreciprocated in one direction, that 1s, during the forcing stroke of thepiston. The head 6 is formed with a screwthreaded openin 9 in which canbe secured the handle 10 (Flg'. 8) so that, when occasion.

member 12 to.,the base.15 as well as acting turn carrying the hea as aclosure for the lower-end of said hollow cylindrical member 12. Thecylinder 1 is orted upon the base 15 by the uprights 16 which arefixedly secured at their lower ends to, the base and at their upper endsto the cylinder.

Mounted upon the base 15 is .a water reservoir17 which is adapted tocommunicate with a pair of forcing pum s 18, 19 operated in alternatedirections. h'e reservoir 17 further communicates with the interior ofthe hollow member 12. The pum s18 and 19 also communicate with the ho owmember 12 for supplying a motive fluid thereto thereby elevating theiston 11, the latter in (i 6 therewith and forcing the material from thecylinder 1 through the spout 4, thatis, if the cut ofi 5 is open. Thecommunication between the member 12 and the pumps 18 and 19 consistsof'a pipe 20 which opens at one end into said member '12 and at itsother end is connected by the 'cou ling 21 to a pipe 22, the latterbeing attac ed to a three-way coupling 23 which in turn is connected toa pipe-section 24. The pipe section 24 is connected by the coupling1pipe section 26 which'communicates with a c eck-valve casing 27, thelatter being in communication, by means of the pipe section28, with thepump 19. The check valve cas' 27 is connected'by a pi e section 29 .to ac eck valve casing 30 an communication between the latter and the pump18 is check valve casings 34 and 35,

had b the pipe section 31. Communicating 3 5 with e pumps 18 and 19 arerespectively the pipe sections 32 and 33 which open into the vrespectively. The check valve casing 34 communicates with 5 a three-waycoupling 36 through the medium with respect-to the "of the pipe section37, and the three-way cou ling 36 is connected with the check valvecasing by the ipe sections 38 and 39. Connected to the t rec-way couplin36 is a pipe 40-which communicates witht ereservo1r'1'7. Within thecheck valve casings 27, 30, 34, and 35 is positioned a-check valve 406), and a stop 41 consisting of a bar which extends across the casing isprovided to arrest the movement of the valve 46 when shifted from off.its seat 42. The valves 40 in the casings 30 and 34 operate alternatelyvalves in the casings 27 and 35. This is owing to the. fact that whenthe latter being in a reservoir the pump 19 is suck- 'e three-wacoupling as connected thereto one en of a ipe 42 which communicates witha cut-.0 43, communication with the 17 through the medium of the pipesection.44. From the foregoing arrangementof iping it will be evidentthat, when the cut-o 43 is closed, the motive fluid will be sucked fromthe, reservoir 17 and forced into the member the pump -18 is forc' mg orvice versa. 23 i1 12 and consequently elevate the piston 11, v,

provided with an 0 which in turn will carry the head 6 therewith andforce the material Tom the cylinder. If it be desired to lower thepiston, the cover 2 is removed, the cut-off 43 opened, and the pistonwill then lower by gravity and at the same time force the motive fluidout of the member 12 and into the reservoir. This will be evident owinto the fact that the check valve 40 (Fig. 6 in check valve casing 27will be closed and the water will ass throu h the pipe sections 20, 22,42, an 44-from t e member 12 into the reservoir 17 Ifthe cutoff 43 isclosed and the pump started the water will be drawn from the reservoirthrough pipe sections 40,36, 37,38, 39, 32 and 33, into the pumps andfrom the pumps forced through the pipe sections 31, 29, 28, 24, 22 and20 into the member 12, thereby elevating the iston, which in turn willcarry the piston hea therewith. I I

The means for o sists of a driven sha t 45 carryin a loose pulley 46,47, respective y, and provided. with a, gear 48 which meshes with a gear49 carried by the pump shaft 50, the'latter being suitably connected tothe pumpsso as to cause them to alternately-o era'te with respect toveach other. tion for this urpose may be employed; The

crating the pumps conpulley 46 is riven by a belt 51 connected to aprime mover, not shown.

A means is rovided to prevent the motive fluid from leakin past thepiston, and such means consists o a double collar 52. through which the(piston 11 extends, and in the channel forme by the outer and innerportions 54, 55, respectively, of the collar an expanding ring 56 ispositioned for retainin "the portions 54 and 55 (Fig. 5) of the co arseparated. The lower eilds of the portions 54, 55 of the collar arebeveled, as at 57. The collar is formed of suitable flexible material,preferably recess 58 formed in the-member 12 near the top thereof. Thedouble collar or what may be termed packing 52 is retained in the recess58 through the medium of a screw-threaded cap 59 which engages with theperiphery of the member 12 atthe top thereof and 1s ening through whichthe piston 11 passes. f the motive fluid should pass upwardly around thepiston it would entei' the recess, and, consequently, ex and the collar52 and cause the portion 55 o the collar to snugly fit the pistonsothatleakage would be prevented.

The means for automatically discontinu ing the operation of the machinewhen the forcmgpiston has arrived at the limit of its stroke in onedirection consists of an automatically o erable belt shifting device forAny suita 1e connecleather, and is mounted within a a fixed and v imoving the elt 51 from off the fixed pulley 46 upon the loose pulley 47so that the operation of the driven shaft 45 will be discontm'ued. Thesaid means consists of a bracket 60 which issecured to the periphery ofthe mg plate 62 which is a ertured, as at 63.

referred to.

The upper face of the p ate 62' is provided with a pair of verticallyextending apertured protuberances 64, 65, the o ening in theprotuberance 64 being of less iameter than the 0 enin in theprotuberance 65. Extending t 011 the protuberances 64, 65 is an actuatinar 66 having an enlar ed portion67 whic extends through the e argedopening in the protuberance65. Mounted upon the bar66 andinterlposedbetween the enlarged portion 67 and t e protuberance 64 is anexpansive spring 68 which when tension thereof is released is ada ted toshift the bar 66 in one direction for a unction to be hereinafter Thebar 66 is retained in normal position so as to store tension in thespring 68 through the medium of a trigger 69 pivoted, as at 70 to theplate 62, and extending in the path of the enlarged 'ortion 67 of therod 66. The lower end of t e trigger 69 is pivotally connected to avertically movable shifting bar 70 therefor.- The latter extends throuhthe lug 61 and is adapted to be engaged y a trip member 71 carried onthe lower end ofa hollow rod 72 projecting from the lower face of thepiston 6 and travelin upon a guide 73 which consists of an upright fixedto the base 15.

Pivoted u on the plate 62, as at 74, is a belt shifter ormed of a handleportion 75 and apairof bars 76, 77, the latter being substantiall L-shaed and having one portion thereo secure( to the formerso as to form thebelt shifter with a yoke-shaped ortion 78 which is ada ted to straddlethe Eelt 51. The bar 76 is a a ited to be engaged by the actuatin rod 66w en the spring 68 is released, whic will cause the actuation of thebelt shifter so that the belt will be moved 4 rom the fixed pulley 46and upon the loose ulley 47. The movement of the arm 76 is imited ineither direction through the medium of a stop 79 formed by a slottedmember integral with the upper face of the late -62 at one cornerthereof. From the Foregoing construction and arran ement of parts it isevident that, when t e piston arrives at the limit of its stroke in onedirec-. tion, the trip member 71 will engage the rod and shift thetrigger 69 vefipn its pivot so that the nose of the trigger be moved outof the path of the enlarged portion 67 of the actuating bar 66 therebyfreeing said bar to the action of the spring 68 so t at the said bar 66will-be actuated an'd the'reby move the belt shifter so as to shift thebelt and discontinue the operation of the machine. I he return of thebelt shifter is had manuall which also cocks the trigger. The be tshifter also provides a means for discontineating uing the operation ofthe machine at any time when occasion so requires irrespective of itsoperation by the trip.
